Quick Summary

Clinozoisite is a monoclinic mineral composed of calcium and aluminum silicate, with the chemical formula Ca₂Al₃Si₃O₁₂(OH). It is a member of the epidote group of nesosilicates and is characteristic of regional metamorphism and hydrothermal alteration of igneous rocks. Clinozoisite occurs as white, green-brown, or gray crystals or masses.12

While clinozoisite shares the same chemical formula as zoisite, it has a different crystal structure. Zoisite has an orthorhombic crystalline structure, whereas clinozoisite has a monoclinic structure.21

zoisite
…the same chemical formula as clinozoisite but has a different crystal structure. All varieties of zoisite have an orthorhombic crystalline structure, which is characterized by three mutually perpendicular axes that are unequal in length. For detailed physical properties, see silicate mineral (table).
